METHOD 0F MAKING ICE-CREAM CONTAINERS.

Application filed November 23, 1922. Serial No. 602,713.

.To all whom it may concern:

Be 1t known that I, 'GEZA IIORVATH, a

citizen of the United States of America, rel siding at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Methods of Making Ice-Cream Containers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to ice cream containers and has special reference to that class of receptacles made of metal and in which ice cream or other matter may be placed or packed.

My invention aims to provide a strong, durable and inexpensive metallic container having reinforced or strengthened upper and lower ends which are made without the use of lead solder liable to contaminate thej contents of a receptacle having parts secured i .together and joints filled by such, a connecting or'filling medium as lead solder. I obviate the necessity of using solder by resorting tospot welding, where necessary, and connecting .the parts in a manner insuring seams or joints that can be readily filled and covered when the interior of the container is tinned or provided with a suitable interior surface or finish, such tending to make the container sanitary in all respects.

My invention further aims to provide the upper open end or inouth of the container with a protecting rim or chime, in the form of a top ring providing an exterior laterally extending bead by which the container may be manually lifted and by which the con' tainer may be prevented from having its side walls injured by adjacent containers.

My invention further aims to provide a container having a lower closed end formed by a bottom piece and ring, the ring being secured within the lower end of the container body. This is accomplished by subjecting the bottom piece to internal pressure causinga wall' of the bottom piece and the wall of the container body to be bulged soY `'that the bottom piece is anchored within the Vcontainer body. Such a constructive arrangement of parts forms the bottom piece as a continuation of walls of .a container body. and when the interior of the body is tinned 0i' otherwise finished the bottom piece of the container appears as though integral with the container body.

Reference will now be had tothe drawe Fig. 2 is an enlarged cross sectional view of the top ring or chime of the container;

Fig. 3 is a similar view of the bottom ring and bottom piece of the container before the bottom piece is anchored relative to the container body;

Fig. 4 is a similar view after the bottom piece has been anchored in the container body;

Fig. 5 is a similar view illustrating an exterior bottom ring that may be used in lieu of an interior bottom ring;

Fig. 6 is an enlarged cross sectional view of a modified form of bottom piece before being anchored in the container body, and

.. f Fig. 7 is a similar View vshowing the bottom piece fixed in the container body.

To put my invention into practice, I provide a cylindrical body or'shell l preferably made from a piece of metal rolled or otherwise brought to cylindrical form with a single longitudinal seam or joint that may be spot welded or the ends of the strip of metal otherwise secured together to forni a strong and durable container body having an upper annular wall 2 and alower annular wall 3.

Mounted on the upper annular wall 2` is a top ring 4 formed with an annular interior vseat `5, an annular exterior bead/or rib 6,

and a chime or rim 7. This Jop ring may be made from a strip of metal rolled to provide the cross sectional shape shown in Fig. 2 and then rolled or otherwise brought to ring form with the ends of the strip of metal connected by a scarf joint welded or otherwise formed. The seat 5 permits of the top ring being seated on the upper edge of the wall 2 with approximately the lower half of vthe top ring surrounding the wall 2. 'Ihe inner surface of the wall 2 will be iiush with the inner wall of the chime or rim .7 and said top ring may be spot welded or otherwise secured to the wall 2 of the container body or shell l. The bead or rib `6 affords an annular reinforcement and hand grip at the lower edge of the top ring and at such a point as to prevent an adjacent container or receptacle, on the saine level, contacting with the container body or shell.

Mounted in the lower end ofthe container body or shell 1 against the wall 3 is an interior bottom ring 8 having a flat bottom wall 9 flush with the lower edge ofthe wall 3. The top wall of the bottom ring 8 is provided with an annular concave seat l terminating in a feather edge lat the wall 3 and this bottom ring may be made from a Vstrip of metalhaving aucrosssectional.shape as shown in Fig. 3 with the strip of metal f rolled `or-brought to ring form with the ends of the strip of metal welded orv otherwise connected, for instance by a spark-or lapped joint.

Thus far T have provided a container body ,or shell with an interior bottom ring, and in order to provide the container' with a bottom a imethod is involved in connection with a sectional, take-apart mold, holder or other annular knock-down 'member 11 provided with an annular forming groovev 12. To :form the bottomof the container l provide :acuppedfor dished bottom vpiece13 having an annular wall 14 with its upper edge bev- -eled,.as.at 15. This bottom `piece .is placed in the kcontainer bodyr i1, on the bottom ring 8, and the peripheral bottom edge of said vbottom Vpiece conforms. in curvature to the :seat 110 of the-.bottoniring 3, with the annular .wall 14 in parallelism with the wall 3,

" as best shown in Fig. 3.5 The bottom piece 13 can be. placed in the container body 1 .berfore .or afterthe container body is placed in the .mold 11. The forming groove 12 ofthe mold is opposite the walls 14 and 3 and as .though the .wall of the groove 12 was a continuation ofthe seat of` the bottom ring 8. Vith these parts so locatedpthe wall 14.

:is .subjected to an internal pressure by a reameror other instrumentality which will forciblyexpand .or distend the walls 14 and 3 into the forming groove 12, causing the `wall 3 Ato be bulgedin the forinationof an exterior annularbead and the wall 14 to be seated infsuch bead 'with its bevelediedge 15 flush with the wall 3thus placing the wall 14 as. a continuation of the wall 3. This is v.best shown in Fig. 4 where the bottom piece 13 assumes al position causing it to be anchored relative to the containerbody, and it vwill be noted that the beveled edge 15 ofthe wall 1:4 meets the wall 3 by a line connection,

:almost invisible in a full sized container and consequently .this Vconnection may be absobe filled during the tinning of the interior walls of the container.

I may resort to spot welding but aside from this it will be noted that the bottom piece 13 cannot become vertically or laterally displaced, and that the connection between the bottom piece 13 and the lower portion of the wall3 is closed and reinforced by the bottom ring 8 yproviding a substantial bottom support for the body of the container.

The same means of subjecting the bottom piece 3 to internal pressure may be used at the upper end ofthe container yfor Yexpanding ,or pressing the wall'2ron to the scat 5 "in :which case a mold 16 will be placed about the topring as abacking kfor such ring dur- .ing the expanding or seating'of thewall2.

Instead of the interior bottom :ring .8 .I may use'anleXter'ior bottom ring or band 17 which is sandwiched between 'the mold )11 and the wall 3 so that When the walls 3 `and 14 are expanded or distended the `exterior ring will also :be expanded .or distended into the forming groove ,1.2 and vthus become yanchored about the lower end of the .container body, providing a three-plythiclmess at the 'periphery ofthe bottompece 13 and a `two- :ply thicknessibelow said lbottom piece. .Spot welding may alsovberresorted'to'as a means of positively connecting "the 4exterior bottom ring 17 tothe zwall3.

As shown vin Figs. 6 and .7 the holder 11 mayhave a `forming:groove 18 of a different cross sectional shape orcontour from the groove f1.2 andthe wall 14 of the bottom piece i13'lias a beveled edge 19 :the yreverseof the bevelededge 15. Infeonsequence ofthe ,groove contour ofthelholder 11 :the Walls 14 `and v3 vcan be pressedinto :the groove 18 until v.the wall 14`is flush withthecontainer body 1, thus eliminating :the curving or bulging vof the 1wall114 as shown in Figs. 4, 5 and 6.

In practice, the parts of fthe container or receptacle are tinned before being .assembled, especially those parts which -are placed nintimatelrelation to formajoint or seam. It .is vtherefore obvious that when the'interior of the container or receptacle is .tinned that such tinning operation .practically .renders the containeror receptacle an integral or homogenous structure. This is particularly true Where seams or tight-joints are welded throughout, in contradistinction to spot ',welcling, and suc-h lthorough ywelding is resorted `to .wherever .it lis necessaryto 'add strength and rigidity -to .parts of thecontainer or receptaclethat willbe subjected-to abuse.

The methodical stepsfthatmaybeaised in the :production of thecontainer 4or like :re-

ceptacle have been brought out .in the appended claims, and whilein .the ydrawing there are illustrated the 'preferred Aembodiments of myinvention, itrisA tolbe understood that the construction and manner of assembling the parts are susceptible to such changes as are permissible by said claim.

What I claim is t 5 A method of making a container consisting in placing a body in a mold having a groove with the body covering the mold groove, placing a bottom ring in said body With the lower edge of the bottom ring flush 10 with the lower edge of the body and an upper curved edge of the bottom ring terminating in substantially the plane of the lower edge of the mold groove, placing a bottom piece in said body on said bottom ring with an annular Wall of said bottom piece parallel With that portion of said body covering the mold groove, and then forcing' said body andV the annular Wall of said bottom piece out- Wardly at the groove of said mold to cause said body and bottom piece to conform in curvature to approximately the curvature of the mold groove and the upper edge of said bottom ring.

In testimony whereof I aiiix my signature.
